INTRODUCTION
MEWOI1330B Large Caliber Wireless H/L Voltage Clamp Current Meter break through the traditional structure, specially designed and manufactured for measuring high voltage current, the unique U-type opening mouth structure realizes the unimpeded measurement, and very convenient for field test. The meter is composed of special large-caliber U-type current meter with high voltage insulation rod, equipped with wireless receiver, which can receive the measured data within 100 meters straight line distance. MEWOI1330B Large Caliber Wireless H/L Voltage Clamp Current Meter used for current measurement of high voltage line below 500kV (connect insulation rod to use), current range: AC 0.00A-9999A, it can directly to test with U-type crrent meter without the insulation rod below 600V. The meter has data hold and data storage and other functions. Insulation rod is equipped with adjustable interface, U-type clamp the tested wire by insulation rod is very convenient, save time and faster. It also can replace the H/L voltage transformation ratio tester, which can measure the H/L voltage current of the primary circuit and the secondary circuit respectively, and then calculate the H/L voltage transformation ratio. The insulation rod is handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on. |
